The Globe and Mail reports in its Saturday edition that Canada's main stock index gave back some of its monthly gain on Friday as declines for financial and technology shares offset gains for resource stocks. A Reuters dispatch to The Globe says the decline came as Statistics Canada said the economy contracted in the fourth quarter. The S&P/TSX Composite Index ended down 161.97 points at 34,339.99. Wall Street also lost ground as worries about credit losses and artificial intelligence disruption weighed. "There is a lot of debate about AI disruption, spending. Some of that is finding its way into financials today as there are some worries that private credit issues may be starting to emerge," said Angelo Kourkafas, investment strategist at Edward Jones. "On the flip side you have materials and energy that are doing the heavy lifting for the TSX as investors rotate into real asset businesses that are less likely to be disrupted by AI." For the month, the Toronto Stock Exchange added 7.6 per cent, marking its biggest monthly gain since November, 2020, as mining shares benefited from higher gold prices and stronger-than-expected bank earnings boosted financials. The Toronto market has advanced for 10 straight months.
